SASH-LOCK.

Specification of Letters Patent.

latcnted Slept. MS, 1913.

Application filed January 21, 1913. Serial No. 743,375.

To zdZ 107mm 2'! may concern:

Be it known that I, Gnonon ili'crnn'r, a citizen of the United States, residing at hfliorgantown, in the county of Monongalia and State of est Virginia, have invented new and useful Improvements in Sash l'iocks of which the following is a specification.

This invention relates to sash fasteners; and it has for its object the provision of a swinging leaf mounted. on the sash and having a free end associated with a sash and adjacent portion of the frame so as to permit the leaf to be conveniently manipulated and further the provision of spaced devices carried by the frame and adapted for interchangeable engagement with said leaf so as to cooperate therewith to hold the sash against sliding movement in either direction, and means forming a part of the leaf whereby the latter will be positively held against being accidentally moved to a re leased position.

Another object of the invention is the provision of a fastener which will be con structed with a view of facilitating the operation of locking the sash in any desired adjustment in the frame.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings :Figure 1 is a front view of a window frame showing the application of the fastener thereto and indicating the position of the movable element of the fastener relatively of the fixed element of the frame, so as to effect a locked condition of the sash; Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1; Fig. 3 a similar View, showing the movable locking element of the fastener adjusted to a released position; Fig. i is a vertical section, taken on the line {L t of Fig. 1; and Fig. 5 is a View similar to Fig. 2, showing the movable element adjusted relatively of the lixed cooperating locking element whereby said fixed element forms an abutment or stop to the movable element to prevent the latter from being accidentally released.

The sash guiding strip 1 on the left stile of the window frame herein illustrated is provided at desired intervals with horizontally extending pins 2, which terminate in outer substantially circular and slightly yieldable heads 3. The lower sash -It has its left vertical bar provided at a point adjacent to the lower corner of the sash with a hinge plate 5 having alined horizontal knuckles (i, which are associated with similar knuckles 7 and connected therewith by a hinge pin 8. The knuckles 7 are foru'ied upon one of the vertical edges of a movable locking element or leaf S) which includes a main body portion 10 having a circular opening 11 therein for the inlerchangea bl e reception of the pins 2 according to the adjustment of the sash desired. The opening if is eccentricallydisposed with relation to the head 3 of the pin 2 whereby a portion of the head will extend laterally beyond the adjacent body portion 10 of the leaf 1) to thereby hold the latter against being :urcidontally drawn over the head 2-} when the sash is vibrated laterally in the frame. The body portion 10 of the leaf is gradually reduced toward its manipulating end 12 and provided with a longitudinally curved linger piece 13, which is adapted to engage against the lower horizontal bar of the sash whereby to hold the leaf spaced from said bar when the leaf is adjusted to an inoperative position. This is desirable in that the operation of adjusting the leaf 9 to an operative position is greatly facilitated, it being understood that the lingers of the hand may be conveniently inserted between the portion l2 of the leaf and the lower horizontal bar of the sash so as to operativcly present the portion 13 for engagement with the lingers.

it is stated that the strip 1 lies in mutual contact with the body portion 10 of the leaf 5) when the latter is associated with one of the pins 2. In this manner, the portion 13 of said leaf will be spaced from the adjacent vertical stile of the window frame to thereby permit said leaf to be elli'ectually grasped by the hand and the required pressure applied thereto to ell'ect its release from the resilient head 23 of said pin.

The head 3 of each pin is beveled in the direction of the shank of the pin, so that the inner surfaces of the head serve as deflecting and guiding surfaces which tend to hold the main body portion of the leaf 9 propcrlv sealed behind the head.

i loving thus tltfitil'lllttl my invention, what I claim is:---

it sash fastener comprising a leaf secured to the sash a leaf hinged to the first leaf and including a main body portion reduced 1n width toward its free end and provided with a curved manlpulating terminal engaging against the sash whereby to hold the 10 able projection into said passage so as to hold the hinged leaf against swinging movement beyond a limited dlstance and to also hold the sash against any sliding movement.

In testimony whereof I affix my signature in presence of two witnesses.
